Abstract

The use of near-infrared lasers and interstitial optical fibers for controlled heating of solid tumors is being developed both as an adjunct to photodynaniic therapy (interstitial laser hypertherrnia) and as a stand-alone modality (interstitial laser photocoagulation). Multiple optical fiber systems, and their use in vivo in muscle and liver tissue are presented, where interstitial thermocouple feedback has been used for direct temperature control as in laser hyperthermia. The tissue response during and after laser photocoagulation has been monitored by magnetic resonance imaging and ultrasound imaging in normal brain tissue and liver respectively, in order to assess the potential for imaging feedback and control. The general concepts of feedback monitoring and control in laser hyperthermia and photocoagulation are also discussed.
